  • Copper homogeneity studies in meteorites

    Creator:
    Wong, Dennis Tung
    Abstract:
    The abundance of copper was determined in four to six one-gram specimens separated by a distance of several inches from each of 23 large chondritic fragments (greater than 1 kg) via instrumental neutron activation analysis and counting of the annihilation N-rays of ⁶⁴Cu. It is believed that an accuracy of...

  • Sodium and manganese homogeneity in chondritic meteorites

    Creator:
    Osborn, Thomas Ward, III.
    Abstract:
    Four to six one-gram specimens separated by a distance of several inches were obtained from each of 23 large chondritic meteorites (approximately 1 kg each) representing the olivine bronzite (H5), olivine hypersthene (L6) and enstatite (E5) classifications. Each specimen was analyzed for Na and Mn via instrumental neutron activation analysis...
